Rejected by her own voters in Wyoming, Rep. Liz Cheney says she won’t remain a Republican if Donald Trump is the GOP presidential nominee in 2024.

“I’m going to make sure Donald Trump, I’m going to do everything I can to make sure he is not the nominee. And if he is the nominee, I won’t be a Republican,” Cheney told the Texas Tribune festival on Saturday.

Cheney has been censured by her own state party and the Republican National Committee for her participation in the House Democrats’ Jan. 6 committee probe after Republicans were denied the right to pick their own members to participate on the panel.
